Meghan, 33, shared the exciting news on her blog and revealed that her one-year-old daughter Aspen is going to be a big sister. "It was so hard for us to keep it a secret from everyone especially since we shared our entire IVF journey with Aspen on RHOC from the very beginning," she wrote. She also revealed that she was one month pregnant while filming the reunion episode of the Bravo reality series.

According to Meghan, who has been very open about her fertility struggles, the couple started the IVF process this past summer. "Opposite of my first experience with IVF, this time I was anxious for the emotional toll while knowing I could handle the physical repercussions," she wrote. "Additionally, I had reliable companionship this time around with Jimmy by my side, my trusty furry companion Girly Girl and of course, baby Aspen. It may seem silly to mention Aspen and Girly Girl but this support system was everything to me during round 2 of IVF."

Meghan and Jim, 47, ended up implanting four embryos, four boys and one girl — so chances are they will be welcoming a baby boy next year. And despite the ups and downs of her fertility treatment, including depression, which was chronicled on RHOC, it was all worth it for Meghan. "Fast forward to today and I am pregnant! I’m not feeling the greatest but we know that it will all be worth it in the end," she added. "Aspen will make a fabulous big sister at only a year-and-a-half old in June 2018! Oh, what about the biggest question: Boy or girl? Think blue this time around!"

Jim is already dad to three daughters, Hayley, Lauren, Sutton, and son Landon, from a previous marriage. Congrats to the growing family!
